mm-Wave Wearable Patch Antenna Design and Analysis for Auditory Applications

In this paper, a novel and small millimeter-wave antenna, which is easy to wear and focused on body-centric wireless communications (BCWCs) is proposed. This antenna, which has an operating frequency of 60 GHz, is constructed on a cotton substrate that is 1.5 mm thick and is 7.0 × 5.05 × 1.5 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup>. It has an outdoor radiation efficiency of 95.61%, a broad impedance bandwidth, and a maximum gain of 6.77 dBi. On a level surface, the antenna's performance is evaluated. Cotton is employed as a substrate because it has been seen to provide a substantial percentage difference of 242.8% at 60 GHz. additionally, five distinct textiles—cotton, and silk, moleskin, denim, and jeans— are used to assess the antenna's performance. The findings of this paper show that this antenna is efficient, compact, and well-suited for integration into wearable systems.
